>Are there things that can happen to both which will really ruin your day?
Yes.
Actually, on 2Sep98, PacBell had a CO failure that knocked out service, in
Livermore, for 12 hours. Voice, data, everything, not even 911!
Not sure how a CO failure brings down leased line data....
What WILL bring down the whole house..:
Fiber cut -- as well as other wholescale transmission
FUBAR's.
Power -- remember the NYC ATT crash? It took hours
to bring the DACS back up... Don't
overlook lightning strikes on the incoming power
feed.
Enviromental -- if the HVAC croaks, if a waterline floods
from the cable vault on up, or there's an
earthquake, or a Hinsdale-style fire.
But such will never happen, so we can all rest easy....right?
What WILL bring down the whole house..:
my favorite was the one byte change to the switch code which took out a big
chunk of the country.

The *whole* CO went off-line.

That wouldn't have taken the entire town off-line.

I would have notice an earthquake, of the fire. The CO's not far from here.

Cascaded failures will do it. aka Murphy having a party.
Are you referring to the 4ESS SS7 cascade crash of several years back,
Randy? I seem to recall that that was more than one character. Couple
of lines.
Now, there _was_ a one character problem in a FORTRTAN program that
killed a space probe...
The Neumann and Lee books are quite good references on this, albeit the
Lee book is a touch sensational.
